Due to its lack of desirable effects on me, I have little to no knowledge of how cannabis, or any of its components or compounds, actually work. Or what they mean. For example, I have no idea what the relationship of CBD to THC is, or even what they stand for. I had to google the Legal Weed drink I had, because I knew it had "40 of something" in it, but didn't know the measurement used. (I think it is 40mg.) So ... I know some of the words in your comment, but am not really equipped with the background info to understand how it applies to me... I feel kinda derpy right now, honestly! :-)
In very general terms: CBD is a semi-legal anti-inflammatory, anticonvulsant, possibly tumor suppressing, pain reducing compound found in cannabis. Delta-9 THC is a psychoactive compound found in cannabis, responsible for the high. Both are found in the plant and breeds have been developed that contain high amounts of either or both kinds. CBD is semi legal, in that you can buy it, possess it, but the process of producing it involves growing cannabis which is still illegal for those of us living in the dark ages. Also, most CBD extract or tincture has some amount of THC present. Not enough to get a buzz, but enough to fail a drug test or catch a felony for possession.
That helps a lot. This makes conversations with my parents (CBD users) and my wife (THC user) make WAY more sense. Yeah, I went to the pot shop to get high. Not to get healthy. So they provided me with the sativa tincture I needed to get my 50mg dose that finally had the desired effect.
